Brake adjustment

If you have front disc, you only need to adjust the rears, there is an oval hole on the backing plate that should have a rubber plug in it, pull the plug and use a brake spoon or a screw driver to turn the adjusting wheel until you can feel a little drag in the wheel. you'll have to have it jacked up to spin the wheel while you adjust. Then step on the brakes to reseat the shoes and check them again.
